Security Camera Offline shows cameras as offline if they haven’t uploaded an image in the last 5 minutes.

Why does this happen? We recommend that you have your camera upload images continuously to at 1 or 2 snapshots per second. This way you can view the live stream on our site without opening your firewall. If you have your camera set to only upload images on motion, then when there is no motion, we’ll show your camera as offline.  See this post about configuring cameras with motion detection for more details.
